End of an era at Domino's

Domino's has been crushing its rival Little Caesars since Patrick Doyle took over as CEO in 2010. His goals were to bake #1 pizzas, improve the dining experience, and build a good leadership team. He scored the hat trick, and shares of Domino's fell 4% yesterday on news Doyle's retiring in June.

On his first day, Doyle acknowledged Domino's was horrible. He changed the sauce and crust. He ordered franchises to redesign the kitchen so customers could see inside. He put live webcams in kitchens so you could watch your pizza being made realtime. He rolled out a feature to order a pizza by tweeting an emoji. Finally, he partnered with the local car company, Ford, for self-driving delivery cars.

The takeaway: Domino's stock rose more than 1,000% with Doyle at the helm. "The tech company that also sells pizza" became Wall Street's darling thanks to Doyle's bold moves. It's the #1 restaurant chain in India, for crying out loud. His successor, Richard Allison, has a cool logo, top digital infrastructure, and 13,811 restaurants globally.

The Kodak blockchain experiment

Shares of Kodak surged after the company's CEO announced a "major blockchain initiative." Photographers "struggle to assert control over their work," so the company said it's experimenting with digital ledgers (the tracking tech behind Bitcoin) to help camera pros more easily get paid when licensing their like-worthy work.

Kodak, which was founded in 1888, failed to recognize the the digital photography revolution and went bankrupt in 2013. Even though the stock's down 73% in the last year, Tuesday's win pumped its value up to $178 million.

The takeaway: Bitcoin is the Viagra of flaccid stocks. Random companies like drink-maker Long Island Iced Tea and biotech firm Riot surged 200% each lately simply on word they may add blockchain technology into their business models. Kodak though is going all in — it's also using an ICO ("Initial Coin Offering") to offer cryptocurrencies for cash to fund its "KodakCoin" project.
